Description

We are sending some binary content out with JAX-RS WebClient. The HTTP transport is http.asyncclient.hc5. Somehow, when I disable allow-chunking in conduit configuration, CXF has org/apache/hc/core5/http/impl/nio/LengthDelimitedEncoder.java involved in the transaction. The transaction fails due to an assertion in the class at assertNotCompleted() at around line#112. It looks like write() in this class is called again after its state is set to complete.

I'm quite sure in my request the content-length of the request is correctly calculated and if I override the class and remove the assertion. My use case works fine. 

The issue also won't happen with any text payload. Is it related to CXF-8629? Please help check.
